-------------
3s + 2d = 4010
2s + 5d = 4800
-----------------------
Modify for elimination:
15s + 10d = 5*4010
4s + 10d = 2*4800
---------
Subtract and solve for "s"::
11s = 10450
s = $950 (cost of one son's meals)
------
Solve for "d"
2s + 5d = 4800
1900 + 5d = 4800
5d = 2900
d = $580 (cost of one daughter's meals)
